Abstract
A stand apparatus for a surgical microscope includes a stand body and a parallel linkage. The parallel linkage is rotatably attached to the stand body by attaching a lower-end joint thereof instead of a vertical intermediate part thereof to the stand body. When the parallel linkage is tilted frontward, no part of the parallel linkage protrudes rearward. Weight balance of the frontward tilted parallel linkage is maintained by, instead of a counterweight, a compression spring arranged along a rear sub-arm.
